Abstract

We report muon-spin-rotation (μSR) measurements of the a-b magnetic penetration depth (

λ_{a b}

) in the vortex state of high quality single crystals of

{YBa}_{2}

{Cu}_{3}

O_{6.95}

. Contrary to earlier μSR studies on powders and crystal mosaics, 1/

λ_{a b}^{2}

shows a strong linear temperature dependence below 50 K which weakens with increasing magnetic field. These results support recent microwave cavity measurements in zero field and provide further evidence for unconventional pairing of carriers.
